IDA-STEP v4.4.x

IDA-STEP v4.4.0 (2011-01-25)

Besides many minor fixes the following enhancements are implemented.

New GD&T view:

presentation (annotations, callouts) in 3D for human interpretation
semantic representation suitable for computer interpretation
creation, modification and deletion of dimensions, geometric tolerances, datum features and datum targets
selection of ISO or ASME format mode
selection of Units (metric or inches)
creation and management of annotation planes
creation of construction and derived geometry (planes, lines, centre axis, intersection, etc.)
GD&T data exchange via AP203 (edition 2) or AP214 (edition 3) files
merging of features (advanced_faces) with the same underlying surface; e.g. two half cylinders into one)
enhanced measurement capabilities beyond what is available in Viewer pro 3D

Significant enhancements for GD&T Editing:

datum feature on dimensions (median geometry)
geometric tolerances on dimensions (controlling median geometry)
added scaling factor to control size of annotations relative to 3D model
ensure that a projected tolerance can only be applied to one end of a hole
selecting bigger or smaller angle dimension
diameter annotations on annotation planes that are in line to the cylinder/circle axis
dimensions to derived geometry and datum targets
changed default colour schema, optimised for annotated 3D model
geometric tolerances and dimensions for a group of objects
creating derived geometry
rotating of annotation planes and updating its callouts

IDA-STEP Viewer Pro 3D:

IDA-STEP Viewer Basic:

General:

many detailed improvements
correcting issues for generated STEP files
create new assembly parts from many given component parts (e.g. for STEP models coming from www.traceparts.com/)c

3D View:

new selection button for annotations
different selection modes can now be enabled simultaneously e.g. edge/cruve with face/surface
exact 90 degree rotation around axis
"Bring to front" for annotation planes
displaying of the annotation planes under the "Annotation Model" combo box. Selecting an annotation model rotates the 3D model so that normal text on the annotation model can be read.

Improvements for GD&T Editing

many small improvements for editing GD&T in general
healing of non-optimal geometry data to enable GD&T editing:
- merging of neighbouring surfaces of the same elementary type (plane, cylinder, sphere) and the same characterisitcs
- converting B-spline surfaces and curves into circular arcs and cylinders if possible
support of tolerances classes for dimensions according to ISO 286
adding of affected plane parameter when creating geometric tolerances of type profile of a line, parallelism, perpendicularity, position, symmetry, straightness
support of dimensions along a curve
updating of already existing GD&T annotations; e.g. to move them on another active annotation plane
GD&T for assembly parts, when all the components are treated as one single piece part.
automatic activation of GD&T perspective when creating GD&T elements
automatic pre-setting the "individual median feature" flag when creating geometric tolerances for
automatic setting the "individual median feature" flag and creation of the median geometry then creating geometric tolerances for feature of size
red-marking duplicated geometric tolerances in the GD&T element table
